Abstract

A compressor unit for underwater operation is provided. The compressor unit includes a compressor having a compressor rotor and a plurality of compressor stages. The compressor unit also includes an electric motor having a stator, a motor rotor, and a gastight housing which is provided with an inlet and an outlet. The motor rotor has two radial bearings, namely a first radial bearing and a second radial bearing, each arranged at the ends of the motor rotor. The compressor rotor has two radial bearings, namely a third radial bearing and a fourth radial bearing, each arranged at the ends of the compressor rotor. A coupling which transmits torque is arranged between the two rotors. The above arrangement provides a remedy for vibrations for especially large compressor units.
